Definitions

  • the invention relates to a closure plate for a sliding closure on the spout of a metal-containing container, with a refractory plate , a sheet metal jacket surrounding it and with an approximately at least partially perpendicular to the plate support formed by the sheet metal jacket centering, which is designed such that the closure plate loose in a metal frame of the sliding closure can be inserted and centered therein at least in one direction; as well as a slide lock for it.
  • a centering means which is characterized by a from the sheet metal jacket or a bandage concentric to the flow opening arranged cylindrical surface is formed. This one at the Plate protruding shoulder formed cylindrical surface is machined so that the plate can be inserted into the metallic frame with almost no play is. With this type of centering, it is necessary that such an approach is available. From this, the shape of the plate can only be changed to a limited extent.
  • the metal housing surrounding the plate below and on the side has one or a plurality of projections, which in corresponding recesses of the metal frame.
  • the metal frame When the plate is inserted, there are Projections in the metal frame with a lateral play in the area between 0.1 and 1 millimeter held in the direction of displacement of the plate.
  • These ledges are therefore to be provided with a narrow tolerance and accordingly they are expensive to manufacture.
  • the present invention was based on the object to create a closure plate according to the type mentioned at the outset, which, with precise centering in a metal frame, is simple and inexpensive can be produced.
  • this closure plate with its dimensions be designed such that the space required stacking of such plates was kept to a minimum can be.
  • the object is achieved in that the centering means by at least two arranged separately from each other at a defined distance Stop faces is formed, which ever transverse to the longitudinal axis of the plate and approximately a thickness like that Have sheet metal jacket thickness, these stop surfaces serve that they for centering the plate on appropriately trained stop surfaces rest on the metal frame.
  • This closure plate can be designed according to the invention easy to manufacture and it's still one of them Centering in a metal frame of the sliding lock ensures that this can be used to work extremely reliably.
  • Fig. 1 shows a section of a sliding closure 10 on the spout Containers containing molten metal, only the latter of the latter outer steel jacket 13 and a refractory perforated brick 17 are indicated.
  • this container is preferably one with molten steel fillable pan for a continuous caster.
  • a refractory sleeve 11 forms the pouring opening 12 from this container. This sleeve 11 closes one Upper closure plate fastened in the metal frame 14 of the sliding closure 10 20 close together, which with a slidable arranged below Closing plate 20 interacts.
  • the lower closure plate 20 serves to open and close the closure 10 and it is to this Purposes in a longitudinally movable as a metal frame 15 Slider unit is held, in which, in addition, one adjoining the plate 20 refractory pouring sleeve 16 is mounted.
  • This slide closure 10 is designed in a conventional manner and therefore not subsequently explained in more detail.
  • the closure plates 20 each have a prefabricated, usually deep-drawn stamped sheet metal jacket 21 and a mortar, plate 22 made of a refractory ceramic material.
  • the Mortar 28 is brushed into the sheet metal jacket 21 in the plastic state and after inserting the refractory plate, it dries and holds the latter stuck in it.
  • This plate 20, which is manufactured separately as a unit, is then produced as a whole loosely inserted into the metal frame 14, 15 and therein it is over a Centering means held at least in the direction of displacement.
  • the closing plate 20 is assigned a centering means, which according to the invention is preferably defined by two in one Stop surfaces 23, 24 arranged at a distance from one another is formed. These stop surfaces 23, 24 rise approximately vertically according to FIG to the plate support 26 formed by the sheet metal jacket 21 and they are each provided approximately with a height like the sheet metal jacket thickness 21 '. These stop surfaces 23, 24 are in the inserted and centered state the plate 20 on appropriately designed stop surfaces 18 ', 19' on Metal frame 14, 15 on, so that the plate 20 is loose and in the direction of displacement is kept almost free of play.
  • the metal frame 14, 15 has for each a protruding nose 18, 19 each with a stop surface 18 ', 19' on.
  • These cooperating stop surfaces 18 ', 19' and 23, 24 are each with respect to the plate support surface 26 as a straight vertical Surfaces formed; they could also be somewhat bombshell or for one Make it easier to place the plate in the frame with a chamfer his.
  • the sheet metal jacket 21 is for formation the respective stop surface 23, 24, each with a separation point and at this each provided with a rib 21 "bent inwards.
  • the one with this separation point The end edge produced in the sheet metal jacket 21 accordingly forms the corresponding one Stop surface 23, 24, which is released by the rib 21 ".
  • the rib 21 "here is bent inwards in such a way that it fits with her lower edge at the end separation point without space to the upper of the sheet metal jacket forming the continuation. This offers the Advantage that there is no mortar 28 between the rib and the sheet metal jacket continuation can penetrate and therefore not stop surface 24 is polluted.
  • This rib 21 "with the corresponding separation point can be due to the Manufacture by deep drawing manufactured sheet metal jacket 21 in one operation.
  • the tool shape that receives the metal jacket and the stamp are designed such that while the stamp is pushed in the tool shape of the sheet metal jacket deep-drawn and on the said point is separated.
  • the one produced with this deep drawing process Stop surface 23, 24 can be processed with a precise without special post-processing Dimensional tolerance in the tenths of a millimeter range.
  • Such Closing plate can thus be easily with this above Equip the centering device described.
  • these two straight elongate stop surfaces extend 23, 24 on the back of the plate at right angles to the longitudinal axis of the plate 21A.
  • they are at the same distance from the pouring spout 12 arranged and provided with a length of approximately half the plate width, which are dimensioned in such a way that they correspond to the respective operating conditions Stop surface 23, 24 of the sheet metal jacket 21 resulting pressure forces can be recorded without deformation.
  • the one stop surface 23 on one and the other stop surface 24 on the other side of the pouring opening 12 is arranged and between them a distance of more than that half plate length arises, and that the stop surfaces 23, 24 of the plates are directed outwards, results in the assembly of the plate 20 in respective metal frame 14, 15 another advantage within the scope of the invention.
  • the plates 20 are in the cold state at room temperature before insertion, meanwhile, the metal frame 14, 15 of the slide closure 10 the pan usually still has a temperature of from previous use about 200 ° to 300 ° Celsius.
  • This temperature difference can the plate can be inserted more easily into the respective metal frame since the Distance between the stop surfaces 23, 24 of the plates to those of the Metal frame is a few tenths of a millimeter smaller than if there was no temperature difference would exist.
  • the plates 20 and the metal frames 14, 15 After putting the sliding lock into operation on the pan and filling the latter with liquid steel the plates 20 and the metal frames 14, 15 at least heat up the stop surfaces 23, 24 to the same temperature, for example approx. 300 - 400 ° C. This causes the plate to expand relatively in relation to the metal frame stronger and she tensions to a certain extent in Metal frame.
  • 3A shows a partial cross section of the centering of the plate 20 in metallic frame 15 transverse to the longitudinal axis 21A of the plate. From this it can be seen that the rib 21 "at a uniform distance from the plate support 26 is formed and the refractory plate 22 preferably on the inside this rib 21 "abuts. This enables, in addition to a parallel alignment a defined distance between the refractory plate 22 and the support 26.
  • the nose 19 of the metal frame and the rib 21 are each with provided such a length that the ends of the rib 21 "on both sides 27 with little play to the outside 28 'of the nose 19 in the inserted Condition of the plate is arranged so that the plate 20 is also transverse to the longitudinal axis of the plate 21A is somewhat centered.
  • the closure plates of the exemplary embodiments explained below 4 to 10 are in themselves similar to those in detail above described plate 20 built. It is therefore only the following Differences and their specific training explained.
  • the fireproof Plates 22 are preferably each mortared in the sheet metal jacket.
  • FIG. 4 shows a closure plate 40 with a centering means according to the invention, in which the two stop surfaces 43, 44 side by side by a strip-shaped rib 41 'of the sheet metal jacket which is bent inwards 41 are formed.
  • This rib 41 ' is laterally through two separation points Sheet metal jacket 41 limited and on one side of the plate support surface arranged.
  • the metal frame 15 in turn has an appropriately trained rectangular nose 36, on each side of which a stop surface is present, which correspond to those of the plate 40.
  • FIG. 5 differs from plate 20, which is shown in detail in Fig.2 and Fig.3, just in that at the ribs 51 "to form the stop surfaces 53, 54 not separating points are provided, but rather that they are groove-shaped in the sheet metal jacket 51 are indented.
  • FIG. 6 shows a closure plate 60 with a sheet metal jacket 61, in which to form stop surfaces 63, 64 two ribs 61 "analogous to those are provided according to Figure 2, but with the difference that both Ribs 61 "on the longer side of the support surface parallel to each other are arranged.
  • FIG. 7 shows a closure plate 70, in which the inventive Centering means in turn as ribs 71 ′′ provided in the sheet metal jacket 71. as shown in Figure 3 - are executed, but these ribs 71 " protrude from the plate 22.
  • the stop surfaces 73, 74 are accordingly formed by the end faces on the ribs 71 ", but the stop faces of the metal frame of longitudinal grooves 79 formed therein are accomplished.
  • FIG. 8 shows a closure plate 80 provided with stop surfaces 83, 84, which differs from that according to Fig. 7 only in its Refractory plate 82 is provided with tooth-shaped reinforcements 82 ', which in the recesses of the formed by the bending of the ribs Protruding sheet metal casing 81.
  • the stop surfaces 93, 94 from one attached to the underside of the sheet metal jacket 91, in particular spot-welded sheet metal strips 95 are formed.
  • This sheet metal strip is 95 preferably rectangular and the side of it as stop surfaces 93, 94 serving end edges are perpendicular to the longitudinal axis of the Plate 90 arranged.
  • FIGS. 10 and 10A show a further embodiment of a closure plate 100, in which the stop surfaces 103, 104 ribs bent downwards 101 ', 103'.
  • These stop surfaces 103, 104 stand out by their circular design, the one formed by them Circle is arranged concentrically to the pouring spout of the plate, thereby It is guaranteed that this opening in the metal frame of the sliding lock is exactly centered and thus the openings of the two closing plates are arranged concentrically to each other.
  • two are symmetrical to the longitudinal axis of the plate arranged ribs 103 ', meanwhile on the opposite Side a rib 101 'is contained in the sheet metal jacket 101.
  • These stop faces could of course also instead of straight or circular be given a different shape.
  • stop surfaces provided on the underside of the plate are advantageous Formed directly on the sheet metal jacket for the purpose of simple production. in the In principle, however, they could also be provided directly on the refractory plate 22 be, especially if the refractory plate 22 in a known per se Way would rest directly on the metal frame 15 and in between not a sheet metal jacket, but only one that encompasses the side of the plate Bandage ring would be provided. The stop surfaces would then be directly in contain the refractory plate 22, in particular through one or two recesses on the underside of the refractory plate 22.
